T 0 ctZZ whom it Til/(by concern:

Be it known that we, PATRICK F. Gurn- RIE and THOMAS Hayes, both citizens or the United States, and residents of Nutley, in the county of Essex and State of New Jersey, have invented a new and improved Waste for Bath-Tubs, Basins, and Like Fixtures, of which the following is a full, clear, andv exact description.

The object of the invention is to provide a new and improved waste or outlet iror bath tubs, basins and like "fixtures, arranged to insure a free outllow of the water l rom the bath tub, basin or like fixture, and without danger of the outilowing water becoming air-bound, and to prevent foul air rising in the waste and passing into the room in which the fixture is located, thus rendering the fixture completely sanitary.

The invention consists of novel features and parts and combinations oi the same which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in. which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the improvement as applied to a bath tub; Fig. 2- is an enlarged sectional plan view of the improvement, on the line 22 of Fig. 1 and Fig. 3 is a similar view of the same, on the line 33 of Fig. 1.

The lower portion of the stand-pipe A is connected, by a waste-pipe B with a bath tub, basin or similar fixture (I, and in the lower end of the stand-pipe A is arranged a valve-seat D leading to the wastepipe E for carrying the waste water to a sewer or other place of discharge. On the valveseat D is adapted to be seated a hollow valve F having a tubular valve-stem F extending up within the stand-pipe A, and provided, at its upper end, with a cap F in which is secured a reduced tubular valve-stem extension F connected at its upper end with a hollow knob G, provided. at its bottom G with outlet apertures G, as plainly indicated in Figs. 1 and 3. The knob G is adapted to be ta en hold of by the operator to lift the valve F off its seat D whenever it is desired to discharge the contents of the bath tub, basin or other fixture C.

On the valve-stem F, immediately below the cap F are formed overflow openings F,

and near the upper end of the valve-stem extension F is formed a valve seat F ,o11 which is seated a ball valve H for normally closing the said extension stem F, the top or which is provided with a cap I having small apertures I for the escape of air from the valve-stem extension F whenever the valve 11 is lifted oh its seat, the said cap I also preventing the ball valve H from accidentally leaving the upper end of the valvestem extension F. The valve-stem extension F passes through a stulling-box J arranged on the bottom of a closure K, preferably in the form of a hollow plug screwed into the upper end of the stand-pipe A, so as to close this upper end 01' the stand-pipe. The top of the closure K is provided with upwardly-extending lugs K, on which the bottom G ol the knob G is normally seated, and in the top of the closure K is formed an opening .li" tor the passage of a guide L, screwed or otherwise secured on the valve stem extension F the guide L normally extending down into the plug K, as plainly indicated in Fig. l. i

The guide .[J is provided, at diametrically opposite points, with wings L extending the length of the guide and passing through recesses K. formed in the wall 01 the opening K, as plainly shown in Figs. 1 and 2. By the arrangement described, the valve-stem extension F the stem F and the valve F are guided, in their up and down movement, to insure at all times a proper seating of the valve F on the valve seat 1).

By closing the stand-pipe A at the upper end and providing a stul'ling-box J for the passage of the valve-stem extension F it is evident that any air or gases rising in the stand-pipe cannot escape unless the valve H is lifted oll' its seat.

As indicated in Fig. 1, the cap I for the valve-stem extension F 3 is arranged within the hollow knob G, and it is evident that when the valve F is seated on the valve-seat D and water passes into the iixture C, then water also rises within the stand-pipe A, and in doing so compresses the air in the upper portion of the stand-pipe, and this compressed air passes by way of the vent openings F into the tubular valve-stem F, fromwhich the air passes up through the extension F to lift the valve 11 oil its seat, and consequently to permit the air to pass out through the openings I in the cap I, and by way of the hollow knob G and openings G to the enter air. Thus, by the arrangement described the water passing into the stand-pipe A can rise freely therein with the water accumulating in the fixture C. It is understood that compressed air in a fixture is liable to force the usual trap or water seal in the waste pipe E and in such an event the foul gases from the sewer readily pass through the fixture into the room.

It is understood that when the water rises in the stand-pipe A, the air passes up through the valve-stem extension F and past the valve H, to escape by way of the cap I and the knob G, and as soon as the air has escaped, the valve H immediately seats itself on its seat F Then it is desired to discharge the water from the fixture C, then the operator pulls on the knob G, to lift the valve F ofi its seat D, and when this takes place the water can readily flow from the waste-pipe B and the stand-pipe A down into the waste-pipe E and to the sewer or other place of discharge.

In practice, the operator pulls the knob G upward until the lower end of the guide L has cleared the top of the closure K, and then the operator gives a quarter-turn to the knob G, so as to seat the lower ends of the wings L on the top of the closure K. By this arrangement the valve F is held off its seat without the operator being compelled to hold on to the knob G. When it is again desired to close the valve-seat D, then the operator turns the knob G back to the previous position, so that the wings L register with the recesses K and then the knob G, extension stem F stem F and valve F are allowed to drop down to their normal position for the valve F to close the valve-seat D.

From the foregoing it will be seen that foul air rising in the stand-pipe A cannot escape therefrom into the room, owing to the upper end of the stand-pipe A being closed by the closure K and the opening in the valve-stem extension F being closed by the valve H, the latter only opening on pressure of compressed air rising within the stem F The device is very simple and durable in construction and composed of comparatively few parts, not liable to get easily out of order. By using different sized plugs K, the device may be readily applied to stand-pipes of different diameters already in use on fixtures of the kind referred to.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. A waste for bath tubs, basins and like fixtures, comprising a stand-pipe having. a connection with the fixture and a valveseat, a valve adapted to be seated on the said valve-seat and having a hollow stem provided near its upper end with an overflow opening and with a reduced hollow extension, a closure for the said stand-pipe and provided with a stuffing-box for the said valve-stem extension to slide in, and a valve in the .said valve-stem extension adapted to provided with a stufling-box for the said valve-stem extension to slide in, a valve in the said valve-stem extension adapted to open outwardly on pressure coming up the said valve-stem and its extension, and a hollow knob for the upper end of the said valvestem extension, the knob having escape openings.

3.
